Hereinafter, it demonstrates in detail so that a person with ordinary knowledge in the technical field to which the present invention pertains can easily implement. However, the present invention can be realized in various forms, and is not limited to the embodiments described here.

The present invention provides a cosmetic composition comprising, as a colorant, a mixture obtained by mixing slag, silicon oxide, silicone oil and an emulsifier and then pulverizing the mixture.

"Scoria" refers to volcanic rock, volcanic sand, A volcanic soil formed by mixing other clays such as volcanic ash and calcining at high temperature.

Slag contains a large number of tiny pores, which are created when volatile components escape from magma released into the atmosphere during volcanic eruptions. Due to this porous structure, the slag exhibits very excellent deodorizing power, adsorption power and sterilization power.

In addition, it is reported that the slag contains weakly alkaline natural mineral components, so a large amount of far-infrared rays are released, and it shows the promotion of blood circulation, metabolism, cell function activation, growth promotion, water molecule activation and aging. and other effects.

The slag, which is a cosmetic raw material, is mainly used as a substance for skin waste or sebum adsorption due to the excellent adsorption force of the porous structure. In the present invention, there is provided a cosmetic composition using the above-mentioned slag as a natural mineral pigment.

The slag has a high reflectance of blue light to impart a natural and translucent feel when applied to the skin, and is insensitive to heat or light to stably achieve hue in the dosage form.

Also, the colorant of the present invention contains silicon oxide, silicone oil, and emulsifier together with slag, and thus has an advantage that the content of other additives such as surfactants and dispersants that induce skin irritation can be minimized.

As the above-mentioned slag, for example, slag found in Jeju Island, Korea can be used. The slag from Jeju Island has a melting point of 1,120°C to 1,210°C, an absorption rate of 17.7% to 32.5% by mass, and may contain various minerals such as calcium oxide, magnesium oxide, potassium oxide, and sodium oxide.

In order to ensure the above effects, 30 to 70 wt % of slag is included in the colorant of the present invention. If the content of the slag is less than 30% by weight, the color tone will be so weak that it cannot function as a colorant. If it exceeds 70% by weight, the content of silicon oxide, silicone oil and emulsifier will relatively decrease, and the colorant will be difficult to be uniform and stable.
